Former Emmerdale actress Roxanne Pallett became 'the most hated women in Britain' after accusing Celebrity Big Brother housemate Ryan Thomas of “punching” her several times "like a boxer", during what he claimed was a simple play fight.

After demanding to be taken out of the house, Roxanne quickly did a U-turn on her words, admitting that she had “got it wrong” before issuing a public apology.

Since then, the 35-year-old has maintained a low-profile, even completely doing away with social media.

But eagle-eyed viewers were left convinced that the star had made a dramatic "return" to TV in Thursday after an unknown person was spotted on the camera.

During a shot where Lewis F walks across the living room, a reflection of a dark-haired person can be seen on the glass behind him.

And according to fans, she looked suspiciously like Roxanne.

Taking to Twitter, one viewer shared a snap of the moment the unidentified individual makes its way on screen.

Next to the image, they wrote: “Can someone explain who this dark haired female is in the background @bbuk #bigbrotheruk I’m confused.”

Immediately viewers began to claim that they believed it to be the former Dancing On Ice Contestant Roxanne.

One user exclaimed: “It’s Roxanne! She’s come back to haunt Cameron!”

Another chimed: “It looks like Roxanne, but if it isn’t Roxanne then who is it?! #BBUK #BBBOTS.”

While a third viewer seemed to agree, simply writing: “Roxanne?”

A final watcher added: “I wondered that!”

Alas, the mystery figure remains… a mystery.

Friday night will see the third eviction of this series of Big Brother.

Housemates Akeem Griffiths, Brooke Berry and Isaac Jagroop are all at risk of getting the boot.
